Diffusion tensor imaging (DTI) has been used to study microstructural white matter alterations in a variety of conditions including normal aging and Alzheimer's disease (AD). White matter hyperintensities (WMH) are common in cognitively healthy elderly as well as in AD and exhibit elevated mean diffusivity (MD) and reduced fractional anisotropy (FA). However, the effect of WMH on statistical analysis of DTI estimates has not been thoroughly studied. In the present study we address this in two ways. First, we investigate the effect of WMH on MD and FA in the dorsal and ventral cingulum, the superior longitudinal fasciculus, and the corticospinal tract, by comparing two matched groups of cognitively healthy elderly (n = 21 + 21) with unequal WMH load...

Hereditary Huntington's disease (HD) is associated with progressive motor, cognitive and psychiatric symptoms. A primary consequence of the HD mutation is the preferential loss of medium spiny projection cells with relative sparing of local interneurons in the striatum. In addition, among GABAergic striatal projection cells, indirect pathway cells expressing D2 dopamine receptors are lost earlier than direct pathway cells expressing D1 receptors. To test in vivo the functional integrity of direct and indirect pathways as well as interneurons in the striatum of male R6/1 transgenic mice, we assessed their c-Fos expression levels induced by a striatal-dependent cognitive task and compared them with age-matched wild-type littermates...

Neuroproteomics is an evolving field of postgenomic medicine, highlighting the convergence of psychiatry/neurology and proteomics, yet compared with neurogenetics, it has received little attention. This study in rat primary neuronal cultures provides an example of a neuroproteomic approach relevant to the study of psychiatric disease pathophysiology, focusing on Alzheimer's disease. In this context, okadaic acid (OA) is routinely used in experimental designs to investigate phosphorylation-mediated events. It is a potent protein phosphatase (PP) inhibitor, particularly of PP1 and PP2A...

Anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED) are the primary eating disorders (EDs). The only psychopharmacological treatment options for EDs with approval in some countries include fluoxetine for BN and lisdexamfetamine for BED. Given the high comorbidity and genetic correlations with other psychiatric disorders, it seems possible that novel medications for these conditions might also be effective in EDs. Areas Covered: The current scientific literature has increased our understanding of how medication could be beneficial for patients with EDs on a molecular, functional and behavioral level...

Purpose The purpose of this paper is to add to the understanding of context by shedding light on the relationship between context and organisational actors' abilities to resolve ongoing challenges. Design/methodology/approach The authors used qualitative data collection (interviews and focus groups with staff and site visits to English forensic psychiatry hospitals) and the analysis was informed by Lefebvre's writings on space. Findings Responses to ongoing challenges were both constrained and facilitated by the context, which was negotiated and co-produced by the actors involved...

Psychiatric bed capacity has decreased nationally with an impact on the number and the types of patients admitted to acute in-patient units. Acute residential programs provide alternatives to hospitals for patients with problems that do not meet criteria for admission. However, these settings may not have resources to respond to the medical co-morbidities associated with severe mental illness. To understand the medical needs of patients in these settings, this research examined data from a nurse-managed primary care outreach service...

In mental health nursing, recovery-orientation is regarded as a best practice approach for patient care. To assess the effect of an intervention utilising a recovery-oriented approach in acute practice, a controlled pilot trial was conducted. On intervention wards, mental health nurses received special training. Recovery Self-Assessment Scale was used to assess the effects of the training. No statistically significant effects were found, between the experimental conditions. Reasons for this result may be methodological, practical or due an intervention that was not powerful enough...

BACKGROUND AND OBJECTIVE: Abnormalities in melatonin levels have been linked to delirium. This dysregulation may be offset with the use of ramelteon, a melatonin receptor agonist. The purpose of this study was to evaluate the role of ramelteon in decreasing the need for as-needed (PRN) use of antipsychotics in elderly patients with delirium. METHODS: This was a single-center, retrospective study involving 488 patients who were placed on constant observation and received care by psychiatric service from May 2015 through October 2015...

REVIEW

Anorexia nervosa (AN) has the highest mortality rate of all psychiatric illnesses due to the widespread organ dysfunction caused by the underlying severe malnutrition. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur. Liver enzymes may also less commonly increase as part of the refeeding process due to hepatic steatosis and can be distinguished from starvation hepatitis by the finding of a fatty liver on ultrasonography...

Autoimmune encephalitis is a group of autoimmune inflammatory disorders affecting both grey and white matter of the central nervous system. Encephalitis with autoantibodies against the N‑methyl-D-aspartate receptor (NMDA-R) is the most frequent autoimmune encephalitis syndrome presenting with a characteristic sequence of psychiatric and neurological symptoms. Treatment necessitates a close interdisciplinary cooperation. This article provides an update on the current knowledge on diagnostic standards, pathogenesis, and treatment strategies for anti-NMDA-R encephalitis from psychiatric and neurological perspectives...

OBJECTIVE: Activation of semantic networks is indexed by the N400 effect. We used a twin study design to investigate whether N400 effect abnormalities reflect genetic/trait liability or are related to psychopathological processes in schizophrenia. METHODS: We employed robust linear regression to compare N400 and behavioral priming effects across 36 monozygotic twin pairs (6 pairs concordant for schizophrenia/schizoaffective disorder, 11 discordant pairs, and 19 healthy control pairs) performing a lexical decision task...

Acute hair felting is a rare disorder of scalp hair. In this condition, the hair becomes twisted, entangled as a hard stony mass resembling a bird's nest. Sudden hair matting has been reported earlier in the literature after vigorous use of chemical and herbal shampoos. Plica polonica is a patchy area of hair matting occurring in due course of time in neglected hair or underlying psychiatric illness. This case is interesting as the whole scalp hair matted immediately after using coconut oil and castor oil following washing...

In neuropathic pain (NP), the atrophy of hippocampus contributes to the comorbidity between pain, depression and the cognitive deficits. However, the exact mechanism underling the comorbidity, the effective control of the degenerations in hippocampus and the remission of the accompanied depressive symptoms are still lacking. Wu-Tou decoction (WTD) has been prescribed for inflammatory pain for thousands of years. In this study, we manifested the effects of WTD on the pain, depression and anxiety co-curative symptoms of NP...

OBJECTIVE: To investigate the effect of chronic comorbidity on the time of diagnosis of multiple sclerosis (MS) and on mortality in MS. METHODS: We conducted a population-based, nationwide cohort study including all incident MS cases in Denmark with first MS symptom between 1980 and 2005. To investigate the time of diagnosis, we compared individuals with and without chronic comorbidity using multinomial logistic regression. To investigate mortality, we used Cox regression with time-dependent covariates, following study participants from clinical MS onset until endpoint (death) or to the end of the study, censuring at emigration...

Terrorist behavior represents a subtype of human aggression probably determined by a combination of biological, psychological, and social factors, as well as by peculiar environmental influences and group dynamics. As regards terrorists' psychological characteristics, the available studies (mostly carried out with no sound scientific design) have failed to identify the common or typical pathological personality traits of modern terrorists. The popular opinion that terrorists must be insane or psychopathic is still widespread; however, no evidence exists that terrorist behavior may be caused either by prior or current psychiatric disorders or psychopathy...

BACKGROUND: Schizophrenia is a psychiatric disorder with a higher mortality than that of the general population. Most of the deaths are due to cardiovascular causes and are related to metabolic risks. This risk is due not only to antipsychotics but also to inherent factors of the disorder. Studies in the West have shown topiramate to be effective in schizophrenia to reduce weight gain and for symptomatic control. Whether this is effective for South Asians is not known. It is important because South Asians have a higher risk of metabolic syndrome...
